ST. LOUIS (KSDK) - Mayor Francis Slay held a press conference Thursday at the St. Louis Emergency Operation Center in downtown St. Louis to provide an update on the city's emergency management preparations.

Mayor Slay says officials are prepared for anything, but are hoping for the best. The main focus at this time is transit, and the afternoon rush hour is expected to be a mess.

Metro transit has been in emergency mode since Wednesday, but is running a full schedule.

Anyone needing assistance should call 211. Call 911 for emergencies.

Mayor Slay says although they are prepared for anything, the biggest concern is an ice storm that could produce lengthy power outages. The city is in close communication with Ameren to stay up to date on current conditions.

Waelterman also urged drivers to stay at home, but if they must be out, to slow down. Unsafe driving can put not only the driver at risk, but also city crews working to clear streets.

St. Louis City Hall and all city offices are closed Thursday, and Maggie Crane, a spokesperson for Mayor Slay, says all non-essential employees are not to report to work due to the winter storm quickly approaching the St. Louis area.

The State Emergency Operations Center has been monitoring the storm since Wednesday morning, and Gov. Nixon has been receiving regular updates from his emergency management team, and officials with the Missouri Department of Public Safety, Missouri National Guard, Missouri State Highway Patrol, and State Emergency Management Agency.

Over 100 flights have been canceled at Lambert-St. Louis International Airport, and more cancellations are expected. American Airlines says they will cancel all flights in and out of Lambert at 3 p.m.
